Possibly a collector car faux pas, but what about something more generic? Have a custom system made so you can get through emissions and then keep the stock system and gut the cat just for collector completeness.

Has the cat collapsed causing the car to run like crap or are you just failing emissions testing?

We don't have emissions testing in my parts. Just looking to be a little enviro-friendly.
